Austin had a local rideshare app that entered the scene when Uber/Lyft left the area because the city passed a law it failed to propagandize against called RideAustin. Non-profit, worked really well and paid well. When Uber and Lyft came back, they heavily subsidized the cost of doing business in Austin by both arbitrarily lowering prices and heavily juicing rewards for drivers. Conveniently, when RideAustin shut down because most drivers and riders had moved onto either app, these rewards started getting clawed back and prices went way back up.
